Avoid duplication of a hidden & inherited prototype's properties.

In Runtime_GetLocalPropertyNames(), the hidden prototypes of an object
are also consulted when deriving the property name set. However, if
given a function object and its template was inherited from the
template of one of its hidden prototypes, that hidden prototype's
property accessors will be present on the object already. Unwanted
duplicates will therefore appear.

Hence, go through the property names that the hidden prototypes
contribute and remove any already occurring ones.

Assumed to be a rare constellation, so the cost of this extra pass is
considered acceptable.

Introduce API to temporarily interrupt long running JavaScript code.

It is different from termination API as interrupted JavaScript will continue to execute normally when registered InterruptCallback returns.

  /**

   * At any given moment V8 can remember only a single callback for the very
   * last interrupt request.
   * Can be called from another thread without acquiring a |Locker|.

Fix Hydrogen SCE pass to avoid eliminating stack guards too aggressively. Only normal JavaScript functions are guaranteed to have stack guard in the prologue. If function is a builtin or has a custom call IC it will lack one.

Changes from r18363:

- includes r18364 to fix compilation errors: removes debugging only code;

- makes interrupiton related tests not threaded, because they rely on having exclusive access to the V8 instance and the fact that they can only interrupt themselves, if they are interrupted from the outside they break;

- changes HasStackCheck predicate used during SCE pass to avoid handles dereference to make SCE compatible with parallel recompilation.
